Hi, when running fop 0.20.4 I get
[ERROR] internal-destination or external-destination must be specified in
basic-link
This is all good, but my document is large and I need to know what link it
is talking about. How would I go about figuring out what link it refers
to? I've been grepping around for half an hour without finding it.
Also, I get
[ERROR] property - "background-attachment" is not implemented yet.
[ERROR] property - "background-position-horizontal" is not implemented yet.
[ERROR] property - "background-position-vertical" is not implemented yet.
when running it. I have not set these, but I guess my stylesheet
(fo/docbook) has. Is this something to worry about?
And what's up with all the empty [INFO] messages?
i.e:
[INFO] [1]
[INFO] [2]
[INFO] [3]
[INFO] [4]
Sorry if these are really newbie-questions, but to fop I am a newbie
Cheers
Nik

Joerg,
Thanks for this. I would never have expected the double apostrophes to
survive, and I've been writing shell for a loooong time, although I
rarely use here documents.

An XPath engine or a very simple style sheet can do the trick.
I have a shell script for exactly this purpose:
cat > $$.tmp << EOF
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:saxon="http://icl.com/saxon"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:svg="http://www.w3.org/2000/svg">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:for-each select="$1">
<xsl:value-of select="saxon:systemId()"/>
<xsl:text>:</xsl:text>
<xsl:value-of select="saxon:line-number()"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
EOF
saxon -l $2 $$.tmp
rm $$.tmp
A java wrapper would do even better (no quoting of the XPath expr.,
get namespaces from the XML doc etc.)
Getting the problematic basic-links is then easy:
query.sh "fo:basic-link[not(internal-destination|external-destination)]" fofile.fo

Hi,
basic-link is "fo:basic-link" so you should not look in your XML file,
but in the FO file that is created. "fo:basic-link" has got an attribute
called "external-destination" or an attributed called
"internal-destination" which is mandantory. Probably they are empty or
not there in your FO file.
Hope this helps,

While it is at least somewhat possible to get some context
from the intermediate FO file, it is next to impossible to
get the position in the source XML (DocBook).
Well, getting to the position in the FO file would already
be an advancement, because some context form there, like
surrounding text or image source hrefs) probably allows you
get to the problematic content in the XML source.

Hei Keiron, thanks for taking the time to answer. :)

While this is a user-list, if some developers feel that they have too
little to do (which I guess is wishfull thinking ;) ) that would probably
be a very nice feature in order to do debugging of XML documents.

Right, so can this indicate that the bug is actually in either the xsl
processor (I've used both xsltproc and com.jclark.xsl.sax.Driver) or the
XSL FO-scheme (I'm using DocBook's fo/docbook.xsl version 1.18 from March
14th) rather than the actual XML document I'm writing? The XHTML-version
is being generated just fine.
> Is it being created by docbook? Maybe there is some missing attribute.
The FO is being created from a DocBook document, yes. What kind of
attributes would normally be missing for such a condition to arise?

The XML document has context information but by the time that handler
for basic-link gets it the information is lost. It is probably possible
to get the information but no one has done it yet.
A basic-link is "a simple one-directional single-target link". It links
to an fo created area using an id or to a URL. I don't know what all
those other terms mean.
Is it being created by docbook? Maybe there is some missing attribute.

Some people like to know how many pages are rendered.

In an XML document, it should definitively have context information. But,
for that matter, what is a basic link? Is it an xref, link, ulink? Is it
an attribute like linkend, xreflabel, id??

Ok, but this wouldn't this only be usefull if there were errors or
warnings on the page?

It would be good if it could somehow tell you where it is but the basic
link doesn't have any context information.
I think the only solution is to search in the fo file. Maybe you need
the right regexp ;-)

Nothing to worry about, it can be safely ignored. Just a notice that
your fo contains things that aren't implemented.

They aren't actually empty the "[1]" means that the page (1) is being
done.
